Activities of "AbpRaven"

How can I mock grpc server for tests? I have 2 microservices and from one of them i send request through gprc to second one. I have overwrited AfterAddApplication. This works but the request is sent to real service and of couse i got exception.

protected override void AfterAddApplication(IServiceCollection services)
{
    _client = Substitute.For<MyClass>();
    var responce = AsyncUnaryCall<SomeClass>(); //responce with real value
    _client.GetAllAsync(Arg.Any<Request>()).Returns(responce);
    services.AddSingleton(_client);
}
